Can you explain the integrated technologies of the Pegasus:Backpack?

核心技术以导航为中心。我们区分室内和室外任务。对于户外，集成多个频段GNSS接收器利用来自全球各地的所有可用GNSS卫星，以在定位准确性方面获得很高的Sigma信心。此外，我们拥有惯性测量单元（IMU），该测量单元由三个陀螺仪和三个加速度计组成，可以在步行和收集数据时补偿运动。

对于室内任务，我们依靠IMU和LIDAR同时定位和映射（SLAM）算法。在扫描和创建地图时，SLAM能够根据LiDAR测量值检测环境并计算轨迹。Pegasus：背包即使在被GNSS的区域中也提供了强大的轨迹。

除轨迹外，我们还有两个激光雷达，每秒收集600,000点和五个自动曝光的高动态摄像机，每个摄像头具有4 mpix分辨率 - 在LIDAR上启用特征提取或超过准确的光程序测量。所有数据都存储在一台集成的多核工业PC中，并带有一台稳定的固态驱动器存储，以便轻松节省任务。

该系统由四个热击电池供电，将四个小时的操作时间扩展到任何所需的长度，只需简单地将放电电池与带电的电池交换。该技术安装在碳纤维一体式底盘中，该机箱非常符合舒适的佩戴。

您如何将地球系统技术与六角形业务技术相结合以创建这种可穿戴的现实捕获系统？bob综合app赌博bob体育报道

我们从在Pegasus中成熟的强烈经验开始：两个，我们知道如何精确管理GNS和IMU数据以计算轨迹并将激光雷达和图像同步为无缝的数据输出。我们将目标设定为高，并希望Pegasus：背包成为第一个可商业可穿戴和室内的系统。

Within Hexagon, we strongly leveraged our Novatel know-how. Together, we tailored the GNSS/IMU calculations and developed our Hexagon SLAM solution. Expertise from different teams within Hexagon led us to make the right decisions.

What makes the Pegasus:Backpack special?

It is clear – the product’s disruptive characteristics. Starting from the futuristic product design to the use of carbon fibre to reduce weight and increase the ergonomic. Continuing with the embedded technology, dual LiDAR, five high dynamic cameras, IMU and SLAM navigation technology, it is a unique data collection tool for the modern surveyor.

这些杰出特征的结合使Pegasus：背包非常多功能用于室外和室内应用程序，使客户能够在现场花费更少的时间，区分其业务模型并在合并市场中保持竞争力。

Can you explain the workflow (data acquisition, post processing, extract information, export to CAD) of the Pegasus:Backpack?

前提条件是让Master GNSS站距数据收集位置或HXGN SmartNet覆盖范围15公里。数据收集不需要测量师技能 - 可以简单地由训练有素的操作员完成。

The operator turns on the system and connects the delivered tablet over Wi-Fi or LAN to the internal PC where the data acquisition module runs – this is the dashboard for data acquisition. Before starting capture, the operator needs to initialise the system, first statically, and then by walking a couples of minutes. After the position is determined, he starts data collection and has full control by the tablet, where he can monitor in real time the images, LiDAR units and GNSS signal strength. Once the mission is completed, the operator does a static end alignment phase and closes the mission.

后处理工作流程高度自动化。通过简单地将USB密钥插入Pegasus：背包，可以下载所有数据并准备好发布后处理。运营商可以预选可交付成果并启动后处理计算 - 无需监督该过程。与SLAM算法接口的强大工具直接嵌入到后处理软件中。它可以在处理和完成数据集之前进行可视化，并在需要时校正SLAM导航。

All industry standard file formats, like LAS, PTS, and E57, are supported and can be exported. Depending on the software solutions used for feature extraction, the Pegasus Software Suite natively produces 3D point clouds and images for ESRI ArcMap or Autodesk AutoCAD.

对于哪些应用，可以使用Pegasus：背包？

The system’s flexibility and ease of use is expanding the applications, going from the most common, for example, professional Building Information Modelling (BIM) documentation, surveying, asset collection, underground infrastructure maintenance, disaster recovery, and safety and security, to more digital reality oriented applications, like industrial training, accidents simulation and urban planning.

您看过Pegasus的最有趣的应用程序是什么：使用了背包？

There are dozens of exciting applications. One of the coolest data collection was in Vars, France, where we provided 3D data for the speed world record attempt in downhill snow mountain biking.

At 3,000 m high, with strong wind, and temperatures around 0 degrees Celsius, a skier was wearing the Pegasus:Backpack and collected the necessary data to calculate a digital terrain model (DTM) that was fed into a Leica iCON controlled snow machine to prepare a perfect slope for the speed attempt.

Another very impressive application was the data collection of the Paris sewers- an extremely challenging environment for humans and the equipment. With the Pegasus:Backpack and the optional flashlight module, we collected a never-before-seen perspective – having the city surface with its buildings and streets and the sewers underground structure in one single 3D data set. The flashlight module delivered crystal clear images unveiling all the manual sprayed notes on the walls. This information was never georeferenced and not visible in any cadastral map. Through the images, it was possible to recognise where maintenance was needed to assure a continued public service avoiding unexpected outages.

客户在此可穿戴现实捕获解决方案中获得的数据做了什么？bob综合app赌博

The Pegasus:Backpack is used to provide multiple, fast and accurate data layers where traditional methods face limits in terms of feasibility, access and costs.

Various customers are using the data for urban area survey, where city centres are only accessible by walking and are closed to traffic or public transportation. An extraordinary application in India is the mapping of overcrowded urban districts. This project provided a detailed cadastral map of the thousands of unknown huts, giving to the habitants an address, name and dignity.

电utility companies are collecting the high voltage power lines to map the infrastructure, analyse the cable sag between two electricity poles, and verify if vegetation is obstructing the right-of-way – assuring a high level of network service availability. Others are taking full advantage of the Pegasus:Backpack indoor capability and collecting entire buildings, verifying the as-built in terms of documentation and square metres per room. Recently, Italian civil protection used the Pegasus:Backpack to quickly get an overview and properly plan the recovery of a devastated city in Italy after an earthquake. All these data use cases have in common the advantage of multiples layers of information provided by LiDAR, imagery, and SLAM or navigation.

Leica Pegasus：背包最近在英国广播公司的意大利无形城市系列中刊登。您能告诉我们更多有关如何Leica Pegasus：两个雷卡·皮卡斯（Leica Pegasus）：背包在揭示这些迷人的意大利城市的秘密方面发挥了重要作用？

It was a fantastic experience working with great professionals. The Pegasus:Backpack and Pegasus:Two were recognised for their ease of use, flexibility, speed and the quality of the data collection they provided. Similar to survey professionals, also in TV shows, production time is related to costs.

当我们在威尼斯捕捉带有飞马的船上的运河时：两天之内，我们在一次捕获中收集了超过10公里的3D点云和数千张图像。我们不必关闭扫描区域，也没有好奇的游客打扰了该系列 - 我们只是在桥下航行，以便能够产生一种新的“运河视图”视角，而传统的捕获方法是不可能的。就车辆和电源独立性而言，灵活性使之有所不同。

在那不勒斯，佛罗伦萨和比萨，挑战是不同的。由于许多历史悠久的欧洲城市，市中心人口稠密，交通封闭，宫殿阻碍了GNSS信号。在那不勒斯，我们收集了地下洞穴，在佛罗伦萨和比萨，我们捕获了室内。仅依靠GNSS/ IMU的技术将无法收集数据 - 使用Pegasus：Backpack，这是一款主场游戏。通过使用SLAM，我们逐步收集并向所有数据收集，并在不需要扫描注册的情况下提供了全面的3D数据集。通过仅穿着12公斤的浅色飞马：背包，我们在15分钟内捕获了Pisa塔的完整螺旋楼梯，其293台阶。
